Am looking to implement a detach and popup UI behaviour in my applcation.
It basically means that I will be displaying say, a stackpanel with lot elements on the right side of my page. And on a button click, I want the stackpanel part to popup(removing its allocated space in the UI) and should be able to move it above the underlying wpf UI.
What am trying to do is that remove the stackpanel from its parent grid on button click and add it as the child of wpf popup control. But I am facing some issues doing this way. However I just want to know whether I am doing it in the correct way or do anyone have a good alternative for implementing this pin out functionality am specified here?
Thanks,

How about using this kinda nice control, AvalonDock, which is simulating Visual Studio's dockable components behaviors?

It will spare you the pain of developing such a specific functionality, and will have a great reusability anyway

Here's what I am trying to accomplish - To create an MDI application in WPF, which can host child web applications. I am using WPF webbrowser control to render web applications. WPF inherently doesn't seem to support MDI applications, so after a bit of searching, I found this project, which uses UI controls to simulate windows and manages them inside a WPF canvas. This approach seems to work reasonably well until I start adding webbrowser control object as an MDI child.
When I add webbrowser control as an MDI child, it always appears on top of other WPF elements including other MDI child controls (as shown below). From what I understand, webbrowser control always appears on top of any other WPF object except for window (and popup). Assuming that's true, I think I need to use actual WPF window to avoid overlapping issue.
The only solution i can think of right now is to wrap WPF window inside an HwndHost object and then add that as an MDI child. However it appears that a child window cannot have title bar. That means that i need to have a window that has a dummy title bar area (just like actual window title bar) and actual content area (which will show webbrowser control) as shown below (Red border is HwndHost object).
This approach seems to solve the overlapping issue. The next thing i need to try is to let users click on the dummy title bar and drag the MDI window inside the canvas element.
Questions -
Is my understanding about WPF webbrowser control overlapping behavior right? If not, what am i missing?
Is the second approach a step in right direction for accomplishing what i want? If yes, how do i implement the drag behavior for HwndHost?
Is there any other alternate solution i can try?
Note:
Although many consider MDI not an elegant solution, I do not have a choice. (We tried alternate solutions like tabbed windows/dockable
windows, but were not well received)
I am quite new to interop programming, and do not understand the
concepts well. Please correct me if i am misunderstanding things.
Thanks!
I have some quite complex content behind several tabs. I'd like to force the layout to happen at application startup rather than lazily as the user clicks a tab for the first time. The delay is about a second or two per tab, and it's a bit embarrassing!
Edit: I think the problem is that only the selected tab's content control is in the visual tree. Calling ApplyTemplate of the HeaderedContentControl didn't make any difference.
Does this link help you?
wpf force to build visual tree
Basically it says to use ApplyTemplate on the ItemsControl...I guess that for the tabs you should do it for each TabItem.
There's also another technique used in this site:
http://xcalibur37.wordpress.com/2012/07/12/make-your-tabcontrol-preload-in-wpf-silverlight/
Here he creates a kind of preloader for each tab. It's for silverlight but I think it can be applied to WPF.
Hope it helps out :)
I'm a WPF newbie and, unlike WinForms, I have a hard time to setup things in the design window.
My first obstacle is the Image control. After I drag it in the Design window it disappears and there's no way for me to edit its properties (like with the button control for example). The only way to make changes is via the XAML code which isn't very visual and intuitive.
Is there a way to keep editing the Image control in design mode? (example, move it around, select it to view its property panel, etc.)
All you should need to do is give the image control a fixed height and width and it should stay in the designer.
The best thing about the XAML is which separated from code for better re usability like asp.net. It's best you to learn different layouts such as grid, wrappanel, stackpanel etc. Then, you will feel the power of xaml. Else, you can choose the XAML building tools.

I am trying to create a WPF wizard control in visual studio. I am successful except I would like to navigate the pages in design time by clicking the next and previous buttons. The pages are being written in xaml. I can navigate the pages by going to the properties window and changing the selected index, but I would like something more user-friendly. I remember doing something similar in a winforms project having something to do with overriding maybe wndproc and listening to mouse click events from the designer.
So I've been googling and I can't seem to google the right words to bring this up.
Can anyone please help!
You need to create a custom Adorner as described here. There are two walkthroughs there that should help.
Ultimately, you would need to overlay a transparent button on top of your actual buttons. Then in the click handlers you'd update your selected item/index.
I'm trying to decide whether I should create a simple StackPanel with Buttons on it, or whether I should use the WPF ToolBar class to contain these buttons (I am creating a simple toolbar).
What are the pros and cons to using WPF's built-in ToolBar control?
So far, these are the only advantages I have seen:
The ToolBars can collapse when necessary; additional items are available from a context drop down.
If the ToolBar is contained within a ToolBarTray, multiple ToolBars can be repositioned relative to each other.
Are the any other benefits to the WPF ToolBar? Neither of these apply to my simple toolbar.
Accessibility might be better with the WPF Toolbar, because it shows itself to Windows UI Automation as a toolbar with toolbar buttons, rather than some random controls. You never know who'll use your software.
Another very small advantage is that buttons in the ToolBar will be styled correctly, whereas the buttons in the StackPanel will take on their default look. Not insurmountable by any means, but a little annoyance none-the-less.
I would say use the Toolbar, because you never know when the next project will come along and need it. You also never know when this project may need it. I don't think there is any real drawback to using it over a StackPanel and the advantage you didn't mention is you'll have more experiance with a built in control for the next project.
On the other hand, I don't see any harm in doing it with the StackPanel, only that if you need to extend functionallity in the future, you'll have to do some rework.
